Wide gear range, low weight and serviceability make the TRSr cassette a great option for 1x drivetrains. The largest three cogs are machined from aluminum for light weight and the smaller eight cogs are steel for durability.

Alloy cogs attach to an XD Driver with a lockring, steel cogs lock in place with a chain whip

Compatible with SRAM and Shimano drivetrains

Steel and alloy cog groups can be replaced independently if excessively worn
